Building & Floor Layout Generator

Most layout tools stop at a single room: you get four walls and a furniture catalog, and the rest of the building doesn't exist. But real layout questions are building questions — where the stairs land on the floor above, whether the office fits six rooms or seven, how the addition meets the existing house, what the lot looks like around it.

RoomSketch3D generates layouts at the scale the question actually lives at. Outline the whole shell, divide every story into rooms with snapping walls, connect the levels with stairs and elevators, and put the yard and property lines around it. Then walk the entire building in 3D — every floor, stacked and furnished — before you commit to anything.

A stacked 2D plan tells you where the walls are; walking the building tells you whether it works. Switch to 3D at any point to move through every floor — up the stairs, into each room — and go back to 2D to fix what felt wrong. If you mostly work level by level, our floor plan generator page covers that single-floor workflow, and the 2D floor plan maker goes deep on precise to-scale drawing.

It's a one-time purchase of $9.99 — no subscription and no free trial. Multi-story buildings, elevators, yards, 3D, and every export format are all included, forever.
